STRAINER FOR PUMPS.

SPECIFICATION forming part of Letters Patent No. 442,052, dated December2, 1890.

Application filed September 11,1890. Serial No. 364 683. (No model.)

To aZZ whom it may concern:

Be it known that I, CLARENCE G. J AYooX,a citizen of the United Statesof America, residing at Albion, in the county of Boone and State ofNebraska, have invented certain new and useful Improvements in Strainersfor Pumps; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

This invention relates to improvements in strainers for pumps.

. The object of the invention is to provide a cheap, simple, andeffective means for keeping chips, dirt, and foreign substances frompassing down. the pipe of the pump, where they would interfere with theoperation of the piston and valves, said strainer being so constructedthat the piston-rod will pass through i the frame supporting thestrainer and will be guided thereby.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical section of a portion of a pump-tube, showing myinvention applied thereto; and Fig. 2 is a detail plan view of thestrainer detached.

This invention is intended more particularly for use in connection withthat class of lift-pumps which have an enlarged cylinder and areconnected to a tube or pipe extending to the surface of the ground,through which the piston-rod passes. The strainer is preferably heldwithin a two-part casting attached to the tube, though in practice itmay be attached to the cylinder.

A refers to a casting, which is made up of the parts a and a, which areprovided with male and female threads Z) and b, the parts at theirjuncture forming a recess B with upper and lower shoulders, againstwhich washers c c abut, a casting O resting between said washers, saidcasting having radial arms 0 and a central hub d, through which passesthe piston-rod. To the under side of this casting and radial arms issecured a disk D, of foraminous material or wire-gauze, which can besoldered to the outer ring and to the radial arms. The upper and lowerends of the casting have openings, which are internally threaded forattachment thereto of the pumptube. The upper casting a is secureddirectly to the pump-cylinder above the piston and valves thereof.

The strainer or wire-gauze being attached to the under side of thecasting C, the arms thereof will receive and hold any material whichwould be of such a weight as to puncture the gauze, and in order thatthe water may pass freely through the wire gauze or strainer the castingA is made of much larger diameter than the pump-tube proper, thetransverse dimensions of the casting corresponding with thepump-cylinder. The piston-rod, passing through the center of the castingG, is guided and cannot contact with the strainer.

I am aware that prior to my invention pumps have been provided withstrainers located above the valve-operating mechanism, said strainersbeing either loose in the pumpt-ube or carried by the piston-rod, and Itherefore do not claim, broadly, a strainer located above the piston andvalve-operating mechanism; but

\VhatI do claim as new, and desire to secure by Letters Patent, is

I 1. In combination with a pump tube, a two-part casting attached tosaid pump-tube and retaining in place a casting 0, having radial arms,and a central hub through which the piston-rod passes, a strainer beingattached to the under side of said radial arms, substantially as setforth.

2. In combination with a lift-pump having a reciprocating piston-rod, atwo-part casting, as described, and a strainer O, and held within saidcasting and provided with a central opening through which the piston-rodpasses, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

CLARENCE G. JAYOOX.
